Polydesmida
Polydesmida (from the Greek language, Greek ''poly'' "many" and ''desmos'' "bond") is the largest order (biology), order of millipedes, containing approximately 3,500 species, including all the millipedes reported to produce hydrogen cyanide (HCN). Description Members of the order Polydesmida are also known as "flat-backed millipedes", because on most species, each body segment has wide lateral keels known as paranota. These keels are produced by the posterior half (metazonite) of each body ring behind the collum (millipedes), collum. Polydesmids have no eyes, and vary in length from . Many of the larger species show bright coloration patterns which warn predators of their toxic secretions. Adults usually have 20 segments, counting the collum as the first ring and the telson as the last ring. juvenile (organism), Juveniles have from 7 to 19 rings. In species with the usual 20 segments, adult females have 31 pairs of legs, but in adult males, the eighth leg pair (the first leg pai ...

Platyrhacidae
Platyrhacidae is a family of polydesmidan millipedes distributed in Southeast Asia and tropical Central and South America. Description Platyrhacids are often large and colorful. They can be distinguished from most other polydesmidans by having ozopores situated further inward from the paranota margins, ozopores surrounded by a broad, flat ring, and presence of compound setae on the labrum and often on the epiproct (a posterior extension of the telson). The gonopods in males are relatively simple, although up to five gonopodal processes ("branches") may be present in some genera from Borneo. Large platyrhacids in Borneo may grow up to long and exhibit colors of blue, green, and yellow with black spots or stripes. Distribution Platyrhacids occur in two disjunct geographic areas. The majority of species occur in Southeast Asia, including the Greater Sunda Islands and the Philippine archipelago. The rest occur in the New World Tropics from Nicaragua to Peru, as well as on some C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parafontaria Tonominea
''Parafontaria'' is a genus of "flat-backed" millipedes (order Polydesmida) consisting of 13 species native to Japan, where they are referred to as train millipedes. This is because some species exhibit periodical swarming behavior during which large numbers congregate and can impact train passage when this congregation occurs on tracks. Documentation of this event goes back to 1920. Individuals vary from around as adults, and feed on leaf litter as well as soil, making them comparable to earthworms in facilitating decomposition and soil nutrient cycling.

Xystodesmidae
Xystodesmidae is a family of millipedes. Its members often have very small distributional areas, with many species only known from a single locality. They are found across the northern hemisphere, with peak diversity in the Appalachian Mountains, where one-third of the 300 or so species occur. They are particularly abundant in deciduous broadleaf forests in the Mediterranean Basin, Africa, Asia, Central and North America, and Russia. Information on basic taxonomy is scant for this family; for example, it is estimated that the genus ''Nannaria'' contains over 200 species, but only 25 were described as of 2006. By 2022, 78 species in ''Nannaria'' have been described. Xystodesmidae contains many colorful and distinctive species, including '' Apheloria virginiensis'' of the eastern U.S. and '' Harpaphe haydeniana'' of the western U.S. The Sierra luminous millipedes of the genus ''Motyxia'' exhibit the only known examples of bioluminescence in the Polydesmida.
